Dysmenorrhea

Dysmenorrhea (or dysmenorrhoea) is a gynecological medical condition characterized by severe uterine pain during menstruation. While most women experience minor pain during menstruation, dysmenorrhea is diagnosed when the pain is so severe as to limit normal activities, or require medication.
Dysmenorrhea can feature different kinds of pain, including sharp, throbbing, dull, nauseating, burning, or shooting pain. Dysmenorrhea may precede menstruation by several days or may accompany it, and it usually subsides as menstruation tapers off. Dysmenorrhea may coexist with excessively heavy blood loss, known as menorrhagia.
Secondary dysmenorrhea is diagnosed when symptoms are attributable to an underlying disease, disorder, or structural abnormality either within or outside the uterus. Primary dysmenorrhea is diagnosed when none of these is detected.
